- group oftubes A is asupporting bed plate. Projecting upwardly from the center'thereof is a rclatively thick perpendicular insulating plate A This plate is centrally 'apertured for a flanged guide sleeve A and there are arranged concentrically about this flanged guide sleeve A a series of conductor tubes A A? arranged in two concentric groups. In my preferred exemplitication, the inner are twenty-four in number and there is one for each hour of the day,

the outer group having sixty in number, one

for caclriiiinute in the hour thou 'h the ar- P1 rangement and number of these tubes might vary depending on the circumstances of their use. These conducting tubes or sockets extend clear through the insulating plate A and are slightly flared as at A on the front side. At the back of the plate, these tubes 'or conductor sockets are provided with integral conductor fingers A A These fingers extend first outwardly from the less than the diameter of the circle in which all the conductor fingers or sockets.

13, which cradle is bolted to. a base as B and to the insulating plate A at 13 B plates, insulating tubes C plate andthen being bent inwardly toward the axis of the central sleeve A fingers are all out of contact with one another and thetubes or sockets themselves are insulated from one another by the plate A Arranged concentric with the groups of contact fingers A A are two continuous conductor collars A A, the maximum diameter of the collar A is preferably a little are located the ends of the fingers A The inward diameter of the collar A is preferably slightly greater than the diameter of the circle bounding the outer extremities of the fingers A The outer diameter of'the collar A is preferably slightly less than the diameter of the circle bounding the inner ends of the fingers A and these two conductor rings mounted as they are on'the insulating plate A are insulated from each other and from Con ductors A A lead from the collars A A? to any suitable mechanism or indicator which is to be controlled by current operated by the switch.

The insulating plate A is held imposition on the base A by a flange B and by a cradle at is a guide ring contained within the cradle These mounted on the-lower half of the front face of the plate A concentric-with the outer diameters of the sockets A in the outer group. Associated with the cradle B is an end plate B closing the outer end of the cradle and projecting upwardly from the bed plate '-A. This end plate is slotted at B, the slot ter minating in a semi-cylindrical end concentric with thesleeve A It is-also bound-ed on its upper extremity by a horizontal bearing surface B.

G is. a program spiders C C at either endjoined by a holding bolt C Clamped between these spiders are alternate insulating plates C and notched conductor plates C At each end are a plurality of heavier insulating plates C C of shortdiameter and there are'spaced along the cylinder similar plates C which divide the notched conductor plates into four separate groups. These notched conductor- .plates and the insulated platesuare perforated as indicated, there being in each plate as many perforations as there are conductor extend inwardly r through the line perforations and contain conductor rods C, each rod being insulated from all the plates except one, the conductor rods and insulating tubes varying in length so that there is one rod and one tube terminating at each conductor plate, rods all projecting outwardly from the end of the program cylinder and being adapted each to penetrate one of the sockets A as indicated. C C are rods carried in the insulator rings or plates C located about the outer periphery of the program cylinder just clearing the notched conductor discs. These rods project also beyond the end of the program cylinder and are so spaced that one of them penetrates the sockets A. .-The inner conductor rods in this case are twenty four in number, there being one notched conductor plate for each hour of the day, the outer rods are sixty in number, there being one for each minute of the hour just as in the case of the sockets above referred to. Each of the conductor plates are notched with sixty notches, one or each minute, one for each conductor rod. is a removable spring contact fork adapted to straddle one of the minute conductor rods, and penetrate its appropriate notch in one of the hour plates, there may be one or more of these forks. They close when in place electric circuits between selected hour plates and mini ute wires and it is by adjusting these various spring fingers that a program may be set up on the program cylinder. The outer end of the program cylinder is finished by a cap C which has a flange bent up around the two insulating plates C adjacent thereto. This flange may be marked toindicate minutes for ease in adjusting or setting up the program, the hours being divided into groups of six by the insulating rings, are easily determined. Projecting outwardly from the end of the program cylinder are two pins C These pins are adapted to engage the horizontal wall B on the end plate B to hold the program cylinder against rotation as it is being positioned. The tension screw C extends beyond such pins and has threaded thereon a hand wheel. C with a channelled hub C adapted to penetrate the notch B and to be guided thereby. The flanges formed of the channel engage the sides of the end plate and hold the hand wheel against longitudinal movement meanwhile permitting its free rotation.

The program cylinder may be disassembled from the rest of the apparatus by rotating the hand wheel to draw the cylinder to the right, guided as it is by the pins C. The contact wires or rods ill move out along the sockets untii drawn, at which position still remai n place being 1 by the pi e other by the ductors C with the guide ring B In this position the program cylinder can be lifted out of its cradle and taken away. When changes or adjustments have been made the cylinder may be returned and held in its.

cradle with the pins C and screw C and hub C engaging the end plate B and the outer conductors C engaging the guide ring B. Then a rotation of the hand wheel will force the cylinder forwardly into position seating all theconductor pins in the sockets. The pressure on the hub C will force the inner flange into a recess C on the inner Wall of the end plate B so as to lock the outer end of the cylinder against displacement in a .vertical direction as shown in the drawings and thus the cylinder will be locked in place at both ends.

The bed A is apertured at D. The'inner end of the aperture is bounded by an upwardly turned perforate flange D in opposition to this flange is a perforateflange D projecting upwardly from a slide D on the bed plate. Thisslide D is slotted at D to engage a ring D on the bed plate and a lock screw D projecting upwardly from the bed plate and associated with a thumb nut D whereby the slide may be moved toward and from the flange D and toward and from the insulating plate A. Projecting upwardly from the slide D is an insulating support D ha ving-a central guide sleeve 1)", a plurality of conductor sockets D concentrically arranged therearound with inwardly extending contact fingers D and a continuous conductor ring D D is a housing and D a conductor leading from a holding screw 1) associated with the conductor ring D.

E is a switch frame provided with pins E E to engage the flanges D D when the parts are assembled as shown. Projecting upwardly from this frame are supporting members E E, ratchet dog supporting members E E and dogs E E The members E E carry an outer switch arbor E and inner switch shaft E associated with ratchets E E and E whereby the arbors E" E may be rotated by an electro magnet E at varying rates of speed. .The outer arbor E carries a switch head E the inner arbor a head E. In these heads are double switch arms E E E and E in electric contact with one another but insulated from the arbors. Thus these pairs of switch arms E E E E serve as the switch arbors are rotated to close electriccontacts l'ietwccn the rings .l-L and fingers A one pair and the rings A fingers A in another pair. Thus when these fingers reach the hour and minute combination selected 7 y i ing of the spring tori C a circthrou 'h between the two conduct-o bly carries a switch head F having insulated switch arms-F adapted to'engage the fin- I C when-thehand wheel C* is rotated to.

gers D and the conductor 1).

When it is desired to disassemble this part of the structure, the thumb, screw D is released, the slide D is drawn'back, freeing the end ot-the shaft E from'engagement with the sleeved)". and the pin-E from engagement with the flange D Then the switch body can be moved slightly to the left freeing the pin-E A The switch fingers pass out freely owingto the concentricity and spacing of the conductor rings and the switch'may be removed t'or adjustment or correction.

It will be evident that while I have shown in my drawings an operative device, still many changes might be made'i'n'the, size,

shape anddisposition of parts without departingmaterially from the spirit of my invention and I wish therefore that my showing be takenasiin' a sensediagrammatic.

The" recess (3 is provided onthe outer "sideol the end plate B to engage the hub withdraw the member C. This prevents upward displacement of the member C until after the pins A? are out of engagement with the sockets A A.
